Work is in full swing at Tucson International Airport as new concessions go up and a major terminal overhaul is underway.

Construction on the concessions areas started March 1, when all of the old concessions were closed and the new operators took over in temporary facilities.

Last September, the Tucson Airport Authority board awarded contracts to operators for new and expanded food, beverage and retail concessions, including local favorites El Charro Cafe, Beyond Bread, The Maverick, Noble Hops, Thunder Canyon Brewery and Arbuckles’ Coffee.

In most of the concession areas, workers have erected construction walls and installed temporary sales areas, though in a few cases new vendors have temporarily moved into old spaces, said David Hatfield, business-development director for the airport authority.

New retail stores on the two concourses are due to open in May, Hatfield said.

The first food concession on the concourses is set to open in July, when Sir Veza’s, Beyond Bread and Pie Five should open on the airport’s A Concourse.

The permanent food concessions on the B Concourse are scheduled to begin construction this summer, with the first to open in the fall, Hatfield said.

Noble Hops and the Arroyo Trading Post, are still in a pre-construction phase in their pre-security area on the ticketing level, but they are slated to open over the summer.

Additionally, an automated vending market in the baggage claim area is due to open in May and Arbuckles’ Coffee, now open in temporary facilities, should open its permanent site by late summer, Hatfield said.

Meanwhile, work is well under way to reconfigure security checkpoints, ticketing areas and concourses under the airport’s $28.3 million terminal optimization project, which is scheduled for completion by the end of the year.
